Map of Magical Activity

"Contain this, or we are exposed and it will mean war."
-- Madam Picquery at MACUSA (WFT)

The metallic Map of Magical Activity used a light display to help Aurors in the MACUSA Major Investigation Department to view magic occurring around New York City (WFT).

Some of the magic shown on the map was undoubtedly from the creatures that escaped from Newt Scamander's case, while other activity might have come from the unknown Obscurial that was attacking buildings and people (WFT).
